(ci. r2-ia4)This invention relates to machines for applying pressure and attachingoutsoles to the bottom surfaces of cement shoes, to the heel seatportions of which high heels already are attached, |`and simultaneouslyfor applying pressure to attach heel breast covering flaps split fromthe outsoles, and more particularly to improvements in a machinedisclosed in an yapplication for Uni-ted States Letters Patent, SerialNo. 785,405, tiled January 7, 1959, upon application of William A.Barker.

T o insure 4a well formed appearance on the tread surface of a shoesole, particularly about the forepa-rt, it has been Ifound mostpractical to employ a solid pad of rubber or similar yield-able materialto press the forepart ofthe sole against the shoe bottom. However, whenit is `desired to press `a breast ap against a heel at the same time asthe forepart of the sole is being pressed against the shoe bottom,breast ap pressing means of a more conveniently adaptable nature thanfound with a solid pad becomes desirable, if the apparatus is to beutilized with shoe heels of widely varying heights, sizes and styles,especially with high strength Neoprene types of adhesives utilized inpresent day cement shoe manufacture, since there is little opportunityto correct misplacement of the breast Hap or to smooth wrinkles formedtherein through improper application of the ap to the heel.

In the machine of the prio-r Barker application a machine is providedwith a pad box, in which there is located in addition to a solid pad ofyieldable material arranged to press the lforepart portion of the soleagainst a shoe bottom, a dilatable fluid containing pad arranged topress the shank portion of the sole against the shoe bottom and also topress simultaneously the heel flap against the heel breast. The solidforepart pad overlies a fluid containing pad which is connected with thedilatable shank pad by a flexible pipe, so that as pressure is developedbetween the forepart of the `sole and the solid pad, the shank pad isdilated and presses the sole and heel breast iiap in a desired manner.To resist the pressure of the shank pad against the heel, so that nodiiiculty is encountered in displacing the heel from proper relationshipwith the shoe, a second dilatable pad is located to engage the rearwardsurface of the heel and is connected through a flexible pipe with theuid containing pad underlying the solid forepart pad. Thus, both theshank pad and the heel supporting pad have introduced into them fluidpressures of equal and opposite intensity.

It has been found that in the machine olf the prior Barker application asubstantial range of 'heel heights may be dealt with, but that thelimits to ywhich the dilatable heel supporting pad is adaptable withshoes having heels of varying heights may not be as extensive as couldbe desired. It is, accordingly, an object of this invention to provide amachine of the type disclosed in the prior Banker application, whichwithout being unduly complicated or expensive may be able to carry outeffectively the simultaneous application of pressures to the forepart,shank and heel breast liap portions of a shoe sole during theirrespective attaching operations on a shoe, especially in cases whereshoes have attached heels of a very high heel type in .the order of fourinches.

In the accomplishment of the above noted and other obiects, theillustrated machine has a pad box carried by `a base supported in themachine frame, shoe engaging and holding devices in the frame oppositethe pad box, main pressure applying means for bringing together the padbox base and the holding devices to attach the sole to the shoe, adilatable shoe shank engaging pad, a second dilatable pad on the base tosupport the rearward surface of the heel on a shoe and a flexible pipeconnected from the shank pad to the heel supporting pad to equalize thepressures therein, in which there is provided a cradle for the shank padmounted for pivotal movement about an taxis extending transversely to ashoe on the shank pad and through the shank pad between the shank andthe heel of the shoe to transmit pressure progressively along Ithe shankof the shoe to the heel Iand downwardly along the breast of the heel toits tread surface as the main pressure applying means acts 0n the shoe.Thus, the angular position of the supporting pad may be changed inaccordance with the requirements for a full range of shoe sizes and heelheights.

ln the machine of the prior Barker application above identified, thedilatable shoe shank engaging pad is hingedly mounted on the mainforepart pad box. When so mounted it is possible to adjust the positionof the shank pad relatively thereto Abut with varying sizes and stylesof shoes it been found that a progressivelyI applied pressure on anoutsole from the area of the shank of the shoe rea-rwardly of the ballof the shoe and continuing along the shank to Ithe heel seat portion olfthe shoe bottom is not always uniformly accomplished. To facilitateprogressive application of pressure in the desired'manner for all sizesand styles of shoe, the shank engaging pad of the present invention isso mounted that it is capable of movement bodily away from the bal-l ofthe shoe as the shank pad becomes dilated `and that the shank of theshoe extending toward the heel seat thereafter has applied to it a soleattaching pressure in the desired sequence.

These and other features of the invention as hereinafter described andclaimed will be apparent from the following detailed specification takenin connection with the accompanying drawings, in which:

FIG. 1 is a sectional view in side elevation of portions of a machinehaving a pad box with a shoe thereon illustrating the features of thepresent invention;

The machine is generally similar to thatl disclosed in the Barkerapplication above identified and is intended for use as a two-stationshoe bottom pressing machine having at each station a carrier 2containing a pad box 4, as Will be described more fully hereinafter. Forapplying pressure against the forepart and shank portions of an outsole6 temporarily secured to a Womans shoe and for simultaneously pressing aheel breast ap split from the outsole against the breast face of a heel8 already attached to the bottom of the shoe the machine is providedwith main pressure applying means arranged in a manner similar to thatshown in United States Letaooalel ters Patent No. 2,047,185, grantedJuly 14, 1936, upon application of M. H. Ballard et al., No. 2,080,035,granted May 1l, 1937, upon application of S. I. Finn, and No. 2,012,272,granted August 27, 1935, upon application of S. J. Finn. The mainpressure applying means is carried by a main frame it) (see FIGS. 2 and4) of the machine.

The main pressure applying means in the construction shown includes apiston 12 slidably mounted within a cylinder formed in the frame and apair of toe and heel engaging abutments 14 and 16 (FIG. l). The piston12 is secured at its upper' end to a base 18 for the pad box. As analternative to the use of a piston for moving the pad box toward theshoe engaging abutments, the pad box may be fixed on the frame it) ofvthe machine and the abutments 14 and 16 may be moved in the frametoward and from the pad box as in the machine of Patent No. 2,047,185.The pressure applying means in the frame of the machine, therefore, maybe in any form which effectively brings together the pad box and the toeand heel holding devices.

The pad box 4 carries a solid upper forepart pad 2i) composed ofrelatively unyielding rubber material resting upon a solid lower pad 22consisting of soft, more readily yieldable rubber. The upper pad 2t) iscovered with a leather shield 21 and is formed with a rearwardlyextending tail 24 which provides an end face projecting beyond the padbox for a purpose which will be explained.

In the machine of the prior Barker application above identified, the padbox is mounted for relative movement in upstanding portions of the padbox base and whenever pressure is exerted on a shoe, the pad box actsdirectly to press fluid from a pad in the base and causes it to dilateother pads both for engaging the shank and heel breast of a shoe beingoperated upon and the rearward surface of the heel to preventdisplacement of the heel from the shoe as pressure is applied by theshank pad.

In accordance with a feature of the present invention the pad box 4 iscapable of being adjusted angularly to accommodate shoes having variousheights of heels or in accordance with other requirements. For thispurpose instead of arranging the pad box for direct engagement with thefluid containing pad, as in the machine of the prior application, thepad box 4 is pivotally mounted in the carrier 2 and is so arranged thatthe for-ward end of the pad box may be raised or lowered to suit therequirements of the shoes being operated upon, the carrier 2 beingarranged to press downwardly against the iiuid containing pad instead ofutilizing the pad box directly for this purpose.

To mount the pad box 4 on the carrier 2 for angular adjustment, thecarrier has vertical flanges having bearing lugs through which passpivot pins 26 on which the carrier is mounted (see FIGS. 2 and 3). Thepins 26 are secured in the lugs of the carrier 2 by set screws 28threaded into the upstanding lugs in the carrier flanges. The pad boxalso has lugs through which the pins 26 pass loosely. At the forward endof the pad box is rotatably mounted in downwardly extending projectionsfrom the pad box a horizontal shaft 30 carrying a pawl 32 pinned to theshaft. The pawl 32 is yieldingly actuated in a clockwise directiontoward a ratchet plate 34 (FIG. 1) secured to the carrier 2, so thatupon raising the forward part of the pad box it swings about the pins26. To facilitate raising the forward end of the pad box, the pad boxhas projecting from it a lifting finger 35, the pawl 32 riding idly overthe ratchet teeth on the plate 34 as the pad box is raised. To retainthe pad box in raised position a rearwardly extending arm of the pawl 32engages a lower end of a spring 35 compressed between the arm and theupper end of a recess in the pad box 4. To lower the pad box about thepins 26, an arm 3S (see FIG. 2) is secured to one end of the shaft 30 tofacilitate release of the pawl from the ratchet, so that the desiredangular relationship of the pad box and the carrier may be obtained. Toprevent the force exerted by the pressure applying means to be applieddirectly to the pins 26, a lost motion connection is provided betweenthe pad box and the pins 26. To this end the pins pass through oversizedopenings in rearwardly extending lugs on the pad box (see FiG. 3

To take up the force exerted by the pres. are applying means on a shoeand to transfer it to the carrier 2 independently of the pins 26, thepad box is provided at its lower end with a downward projection 39 (seeFIG. l) arranged to engage an angular surface 40 on the carrier 2. Whenthe pad box is in its lowermost adjusted position a surface 42 on thepad nox engages a face 44 on the carrier. To enable these forcereceiving surfaces to engage firmly the openings for the pins 26 in thepad box 4 are made relatively large for ample lost motion between thepad box and the carrier 2. As the pad box swings about the pins 26 thesurfaces 39 and 40, therefore, are enabled to be continually inengagernent.

The fluid containing pad of the present machine is mounted in the baseof the pad box as in the machine of the prior Barker application. Thisiiuid containing pad is indicated at 46 and is formed in part by thebottom surface of the base and in part by a rubber diaphragm 4S clampedin fluid-tight relationship with thc base. To suspend the carrier 2 andmaintain it in proper relationship with the fluid containing pad 46vertically spaced lugs on the carrier have connected to them two pairsof horizontal links 49 (FIG. 2) which act to maintain the carrier in alevel position with freedom for vertical movements.

To cause pressure to be applied to the shank of a shoe being operatedupon progressively from the ball portion of the shoe to the heel seatand thence along the breast of the heel to its tread surface, the ballportion of the shoe is engaged with the tail 24 of the upper pad 20 atapproximately the midsection of the shoe shank and the shank surfaces ofthe shoe are engaged by a shank pad 50 carried by a confining cradle 52having a mounting supported in accordance with a feature of the presentinvention about the pivot pins 26 on the carrier. The mounting for thepad box is arranged in such manner that automatic adjustment is providedfor the shank pad lengthwise of the shoe and manual adjustment isprovided for the shank pad heightwise of the shoe. For this purposethere is rotatably mounted on the carrier 2 by means of the pins 26 ayoke 54 having horizontally spaced parallel arms and a downwardlyextending sector portion which connects the arms for joint movementabout the pins 26. Also, formed integrally with the yoke 54 is an armcarrying a spring pressed pin S6 engageable with any one of a series ofopenings 57 in the carrier 2. At the rearward end of the parallel armson the yoke 54 are a pair of rolls 58 (FIGS. 2 and 3), one of which isbeveled and the other fiat edged, engaging grooved and fiat surfacesformed on shoulders 59 (FIG. 5) on the cradle 52 projecting over therolls and having abutments at the ends of the shoulders to limit themovement of the cradle along the rolls. The downwardly extending sectorof the yoke 54 also serves to support adjustably the tail 24 of theupper pad 20 and to maintain the tail 24 of the upper pad in contactwith the cradle for the shank pad.

The cradle enclosed dilatable shank pad 50 is yieldingly held inengagement with the rearward end of the tail 24 of the upper pad 20 by apair of springs 60, each stretched between a hook or pin fixed to thecarrier 2 and a hook projecting from the cradle 52. Thus, the cradlenormally assumes a position at the limit of its forward movement beforepressing a shoe after it is introduced into the machine, and the shankpad is capable of being expanded against the tail 24 of the upper pad ina rearward direction progressively against the breast of the heel. Theinterior of the dilatable shank pad 5t) is connected by iluidtransmitting means, including a tixture 62 (FIG. 5), a flexible pipe 63,and a lixture 64 (FIG. 3) leading into the uid containing pad d6. Aspressure is developed by torce applied to the fluid containing pad, thedilatable shank pad becomes enlarged, applying pressure progressivelyalong the surface of the shank to the heel and downwardly along thebreast of the heel in a desirable manner. Expansion of the shank padtends to move the cradle containing the pad bodily in a rearwarddirection guided by each shoulder 59 and roll 58. By so doing theoperation of the dilatable shank pad is improved over that produced bythe shank pad of the prior application, in that greater uniformity andreliability of progressive action is provided.

To mount the rolls 5S on the yoke S4 the arms have secured to them apair of studs 65, one at either side of the cradle 52, the rollsrotating on the studs. By this construction the cradle is held at alltimes in engagement with the tail of the upper pad 26'.

In order to support the heel of the shoe against displacement as theheel breast ap is pressed against the face of the heel by the dilatableshank pad 56, a second dilatable rubber' pad 66 is arranged forengagement with the rear curved surface of the heel and a part of theheel end oi: the shoe upper lying about the heel. The pad 66 is held ina cradle 68 mounted for pivotal movement about a pair of pins 76 (FIG.2) projecting laterally from the cradle 66 and passing through forwardlyprojecting arms of a slide 72. The slide 72 is mounted on a guideway 74(see FIG. 4) and the slide has mounted at its rearward end a horizontalrockshaft 76 along the central portion of which is secured a pawl 73.The pawl 78 is disposed above a series of ratchet teeth 80 to lock thepad 66 from separation from the rearward surface of the shoe heel duringoperation of the machine. To actuate the slide and pad 66 toward andfrom the heel of a shoe the rockshaft 76 has at its ends a pair of arms82 pivotally connected to a pair of links 84, in turn pivotallyconnected to the upper ends of a pair of arms S6. The arms 86 aresecured to a iorizontal shaft 83 rotatably mounted in the pad box base13 and at the rear-ward end of the shaft 8S there is secured an arm 90pivotally connected through a link 92 (see FIG. 4) to a block Siesecured to the upper end of a headed rod 96 slidingly supported in aplate 98. The plate 98 is in turn secured to the frame 10 of themachine. Below the plate 98 the rod 96 is surrounded by a spring 160.During operation of the machine, as the base 18 moves away from theframe 10 the heel supporting pad 66 is moved against the rearwardsurface of the heel until it engages the heel and thereafter the spring100 is compressed without moving the heel supporting pad 66. Besidesmoving the pad 66 toward vand from the shoe heel, the connectionsdescribed raise and lower the pawl 78 with relation to ratchet teeth 80on the guideway 74 to lock the heel supporting pad in engagement withthe shoe heel. During the return movement of the base 18 towards theframe 1t), the connections disengage the pawl 78 from the ratchet teeth8@ and move the heel supporting pad rearwardly. To limit the rearwardmovement of the heel supporting pad the guideway 74 has secured byscrews 102 (FIG. 4) to its rearward end a stop plate 1M against whichthe pawl 75 strikes during the return movement of the pad.

To bias the pawl 78 for movement toward the ratchet teeth Sii, one ofthe arms 32 has a pin, between which and a pin on the slide 72 there isstretched a tension spring 165.

ln the case of a machine in which the shoe engaging abutments Ji and 16are raised and lowered and in which the shoe remains stationary, insteadof operating the heel supporting pad 66 through connections between thepad bex base and the machine frame, there may be provided additionalconnections controlled by the operator in starting the machine. In thiscase a starting treadle is connected to the slide '72 on which the heelsupporting pad is mounted in such a way that the heel supporting pad isengaged with the shoe heel before the sole attaching operation isstarted.

The dilatable heel supporting pad 66 is for-med with a thickenedforwardly facing wall (FIGS. l and 6) covered with a sheet of leather106, the margins of which are Secured to the cradle 68, which is in theform of 'a hollowed out enclosure. The fonm of the heel supporting pad66 is more clearly illustrated in FIG. 7. At the top of the pad theiluid transmitting means is continued through a flanged nipple, theflanges of which are also secured to the upper surface of the enclosureby a clamp block 108 having a threaded outlet from the pad engaged by alixture 110 (FIG. 4). rl`he fixture 116 has engaged with it the upperend of a flexible pipe 112, the opposite end being similarly connectedto a fixture 113 (FIG. 3) entering the uid containing pad 46. By meansof the pipes 63 and 112 and a `free fluid passage through the pad 46,the Huid pressures in the shank pad 5G and the heel supporting pad 66are equalized and the forces exerted on the heel breast and rear surfaceare substantially balanced. Thus, the tendency to displace the heel 8from a shoe being operated upon is reduced to a minimum.

By reason of the pivotal mounting provided by t ,e pins 76) which passthrough the lower end of the cradle 68, the pad 66 is hinged for angularmovement, so that its heel engaging face can be adjusted to assumedifferent degrees of inclination to the horizontal. When the heelsupporting pad has been adjusted to the desired angular position, it islocked against further movement by a pawl and ratchet, the pawl of whichis indicated at 114, and the ratchet of which is in the form of atoothed plate 116 secured to the slide 72. The pawl is secured to ashaft 117 rotatable in the cradle 68. In Order to release the pawl 114from the ratchet plate 116 and to allow the heel supporting cradle to beswung about the axis of the pins 70, the pawl supporting shaft 117 hasfixed to one end an arm 118 having a handle by which the shaft can beturned in a counterclockwise ldirection as viewed from FIG. 2, thusmoving the pawl clear of the teeth on the ratchet plate. To draw thepawl against the toothed plate 116, a hook made fast tothe shaft 117 hasstretched between it and the cradle 68 a tension spring 119.

The heel supporting pad 66 is arranged to move downwardly with the shoeduring the sole attaching operations, as in the machine of the priorBarker applic-ation. For this purpose the guideway 74 is supported bytwo sets of parallel links 120 `and 122 pivotally connected between theguideway 74 and the opstanding lianges of the base 1S. To maintain theheel supporting pad and the guideway '74 in raised position before asole attaching operation is started, the links 120 at their forward endsand the rearward ends of the links 122 have attached to them hooksbetween which are stretched coil springs 124 (FIG. 4) at either side ofthe guideway 74, the action of the springs tending to olfset the weightof the heel supporting pad and the slide 72.

Refer-ring more particularly to FIGS. l, 5 and 6, the shank pad 50 hasits heel engaging wall of varying thickness along the length of a shoeheel, the wall being thinnest at its upper end where it merges with theshank engaging portion of the heel, and becoming gradually thicker in adownward direction toward the lower end. iIn this way the heel engagingwall can yield and act progressively against and downwardly along thebreast iiap supported by the heel as the fluid pressure graduallyincreases within the shank pad.

The heel supporting pad 66 has its heel engaging wall of substantiallyuniform thickness from its upper to its lower end as distinguished fromthe heel engaging wall of the shank pad. The heel supporting pad ditfersalso from that disclosed in the prior Barker application, in that itoverlaps the upper portion of the heel and covers a substantialproportion of the shoe upper above the heel. Such an arrangement isadvantageous in preventing displacement of the heel from its seat duringthe soie attaching operations and also, in general, in resistingmovement of the shoe in the pad as the pressure on the shoe isincreased. Such an arrangement also makes it desirable to adjust theheel supporting pad in an angular direction in order to accommodatedifferent styles and sizes of shoes, especially where shoes of largersize have different curvatures along the rearward surfaces of the heelfrom shoes of smaller size.
